The new Watt seat - more backward and anatomical - allows the triathlete to avoid possible friction during the push phase and, combined with an enlarged nose (50mm), to benefit from greater comfort without altering performance. The Watt Gel Superflow is equipped with a particular layer of gel inside the padding that allows you to benefit even more from the feeling of comfort and to maintain performance even on the long distances.

Selle Italia saddles come in three sizes:
And they have three configurations:
No cutout (1)
Small Cutout (Flow / 2)
Large Cutout (Superflow / 3)
So if we decode a Selle Italia SLR Boost S3 - that's a Boost saddle in narrow with a large cutout 9Superflow).
They have a very handy tool on their website that will work out exactly what size you need. It only takes 30 seconds to complete and is well worth the effort to make sure that you buy a saddle that is perfect for your body type. Find the tool by clicking here.
